T 0 all to 7mm it may concern:

Be it known that I, Crrns'rER D. Horn, a citizen of the United States, residing at Winchester, in the county of Grant and State of Washington, have invented a new and useful Appliance for Cleaning Tubes, of which the following is a specification.

This invention relatesto a tire repair tool and has for its object the provision of a device in which the implements necessary for the application of a patch to an inner tube are assembled in convenient and compact form.

Other objects will present themselves as the description proceeds, it being within the province of the disclosure to improve generally and to enhance the utility of devices of that character to which the present invention appertains. It is to be understood I that, within the scope of what is claimed, slight changes may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawing forming a part of this specification:

Figure l is a longitudinal section through the device.

Figure 2 is a view in elevation of the upper portion of the tool. i

Figure 3 is a view in side elevation of the device.

Figure 1 is a view depicting the manner in which the device may be used and Figure 5 is a view in end elevation.

Referring to the drawing by characters of reference, the bodyof the device comprises a tubular container 1 having an open end 2 provided with screw threads 3. The said container forms a handle for the tool and is adapted to hold repair material, including patches, cement. etc.

A second container 4, having a closed bottom 5, is screw threaded at 6 to match the threads 3, the said bottom forming a closure for the container 1. The container 4 provides a reservoir for supplying gasoline used in cleaning a tube to be patched and has screw threaded to its upper open end a brush holder 7 which forms a closure for the reservoir. The brush holder is provided with a central socket 8 in which an applying member, preferably in the form of a brush 9 is seated.

A small hole 10 opens through the bottom of the socket to supply gasoline to the brush or mop. A cap 11 is screw threaded at 12 Application filed October 20, 1921. Serial No. 509,093.

A scraping element 13 secured to the brush holder 7, adjacent its connection with the reservoir, serves to being used in conjunction with the brush m a combined brushing and scraping operation. It will also be noted that the scraper 13 provides a stop or rest to prevent rolling of the implement when placed on an inchned surface.

A bufiing or roughening attachment 14 is also carried by the brush holder, the same having an active face 15 arranged at an acute angle with respect to the handle. A downturned flange 16 stiflens the buffer and contacting with enlargements 17 and 18 on the members 4 and 11 respectively, serves to prevent said members from becoming loose,

or unscrewmg.

In preparing an inner tube for the application of a patch the tool may be used as illustrated inFigure 4:, the brush applying the cleansing fluid and being followed by the buffer or roughener so that the cleaning and roughening operation may be carried on s multaneously, likewise, it will be noted, that when the tool is used as illustrated in Figure 4, a partial rotation of the same may be made to bring the scraping element into action, it being unnecessary to remove the brush from the work or to materially chan e the angular relation of the handle to tl ie work.

As shown in Figure 5 the buffer and scraper also form means for conveniently and securely it is desired to apply the brush holder to the body or remove the same therefrom. As illustrated the thumb is placed on the roughened portion of the buffer and the first QFFI fluid and protects the assist in cleaning the tube,
